Blackfoot Ultra — "Death by 100 Hills" — is an ultra-trail and community race held at Blackfoot Recreation Area near Islet Lake, east of Calgary. Created in 2002 to highlight the region’s trail network, it features mountainous terrain with significant elevation change, earning its reputation as a premier Alberta ultra.
On-course aid stations offer electrolyte drinks, water, Coke, ginger ale, fruit, cookies, chips, sandwiches, soup, and pickles.
Pacers are assigned by start wave (Startwelle): refer to the "Renntag für Laufende" schedule for specific target times per pacer group; pacer flags will be displayed on course.
Monthly averages based on historical data (2000–present).
Yes — since 2009 every registered racer must commit to four hours of volunteer time (can be completed any time between the prior year’s race and April 30, 11:59 pm of race year). Volunteer roles include race support, trail maintenance, coaching, officiating, or community clean-up.
Drop-downs are allowed for ultra distances until May 10 of the prior year: 100 km → 50 mile/50 km/25 km; 50 mile → 50 km/25 km; 50 km → 25 km. No refunds for drops; 25 km cannot be dropped down. Changes require contacting race organizers.
Registrations are not transferable. A 75% refund is available if you email the race before March 1 of the race year; after that, refunds are not offered except for expectant mothers and active military.
Bring headlamp (useful for pre-race check-in and outhouses), required race gear per rules, and optional nutrition. Aid stations provide electrolyte, water, Coke, ginger ale, fruit, cookies, chips, sandwiches, soup, and pickles.
